cwall_north: Cwall north-facing

In paulnorthrop/walls: Statistical Inference for the Thermophysical Properties of Walls from In-Situ Surveys

Description

Long-term in-situ measurements of heat flux and temperature on a filled cavity wall in a residential building in the UK, between 14:00 on 12/03/2015 and 13:55 on 30/08/2015 inclusive.

Usage

cwall_north

Format

A dataframe with 49248 rows and 5 columns.

• Column 1, Time: in format DD/MM/YYY HH:MM. The time step is 5 minutes.

• Column 2, Q_out: heat flux density into the external surface, in watts per metre squared.

• Column 3, T_out: temperature of the external surface of the wall, in degrees C.

• Column 4, Q_in: heat flux density entering the internal surface, in watts per metre squared.

• Column 5, T_in: temperature of the internal surface of the wall, in degrees C.

Note: In the modelling equations in Gori (2017) the variable Qout is the heat flux out of the external surface of the wall. Therefore the Q_out values in column 2 need to be negated before using these equations.

There are three pairs of times for which the data are missing:

• Rows 1487 and 1488: 17/03/2015, 17:50 and 17:55

• Rows 14369 and 14370: 01/05/2015, 11:20 and 11:25

• Rows 41798 and 41799: 04/08/2015, 17:05 and 17:10
